SMOKING-PIPE.

Specification of Letters Batent: 1 Patghted A g. 31 1915 Applicationfiled August 6, 1914. Serial No. 855,456.

This invention relates to smoking pipes and to a cleaner therefor, thecleaner being adapted to be removably carried in the pipe and the pipebeing arranged so as to be capable of receiving the cleaner for thispurpose.

The invention consists of the particular construction of the parts ashereinafter described and claimed and as illustrated in the accompanyingdrawing in which:

Figure 1, shows in longitudinal section a pipe of conventional type,embodying the features of my invention and with the cleaner in position.Fig. 2, is an enlarged end View of the mouth piece of this pipe. Fig. 3,is a top view and Fig. 4-, is a side view of the mouth piece as itappears in Fig. 1. Fig. 5, shows the cleaner removed. Fig. 6, is anenlarged cross section of the shank of this cleaner. Fig. 7 showsmanipulation of the cleaner for the purpose of inserting the same intothe pipe. Fig. 8, shows a modified construction of the cleaner.

In the drawing numeral 8 indicates the bowl of the pipe.

9 indicates the shank or stummel thereof and 10 is the mouth-piece.

The cleaner consists of a number of spines 11 of steel wire closelybunched at one end and held together by a tubular socket 12, the latterbeing compressed after the spines are inserted to hold them firmly inplace as indicated in dotted lines in Fig. 6. In the construction shownin Fig. 8 they are bound together between their ends. This socket formsthe shank of the cleaner whereby it is heldwhile manipulated forcleaning the pipe. In their normal condition the free ends of the spineshave a tendency to spread as shown in Figs. 5 and 8. For in sertion ofthe cleaner, the free ends of the spines are held together as shown inFig. 7 to facilitate their entrance into the mouthpiece. One of thespines is extended beyond the outer end of socket 12 and bent away atright angles to form a short catch 13 to facilitate withdrawal of thecleaner from the pipe in the manner indicated in Fig. 3. In.

the normal condition and when the cleaner occupies its position withinthe pipe, this catch rests in a groove 14 in the end of the mouth-piece;In thisposition this catch is not noticeable and does not become0bjectionable. i

The cleaner is of a length, that when so inserted, the free ends of thespines extend into the bottom of the bowl of the pipe.

-The bore which forms the draft duct for the passage of smoke throughthe stummel and through the mouth-piece is of a diameter which preventsinterference by the inserted cleaner with the drawing of smoke throughthe smoke duct when the pipe is used. The elastic tendency of the spineswhich causes them to spread holds them in close contact with the sidesof the smoke passage so that the cleaner readily retains its position.Occupying a position as they do, and where obstruction mostly occurs inthe draft duct, namely where it joins the bowl, these spines reduce thispossibility and when obstruction occurs their withdrawal causes alsoremoval of the obstruction at once- Furthermore being of metal thespines become hot reduce thereby accumulation of moisture and tend tokeep this part of the duct and the lower part of the bowl comparativelydry. Farther up in the duct, these spines act as a trap by interceptingnicotin-carrying moisture which condenses and accumulates on them sothat when the cleaner is withdrawn for cleaning, the larger part ofaccumulated matter passes out with it.

The cleaning effect may be increased by turning and twisting the cleanerduring the act of withdrawing it. After withdrawal, it is readilycleaned by wiping or by holding it under running water. The cleanerbeing flexible accommodates itself to any shape of the mouth-piece orstummel and readily follows this shape if these parts are curved. v v

The cleaner may obviously be used independently and on any other pipenot necessarily the one in which it is carried and with any possiblemode of manipulation, as for instance, the mouth-piece havingbeendetached from the stummel, each of them may be cleaned separately. Inthis mode of manipulation the cleaner, if carried in the pipe, becomesreadily accessible after the mouthpiece is detached, so that the use ofcatch 13 is not necessarily required for In combination with a pipewhich com-' prises amouth-piece provided with a groove extending fromthe duct-opening therein across its end, a cleaner consisting of aplural y of pin f-Qli S rebu h and hel d'together at one endand adaptedto co cupy the smoke duct ofsaid' pipe in which the cleaner-isremovablyheld by the spreads ingtendency of its spines and bytheinconsequential contact with the sides of the smoke duct, one of saidspines being longer and extended beyond the mouth-piece and bent to forma catch to facilitate removal of the cleaner, said catch in normalcondition occupying the groove in the mouthpiece mentioned. 1 i
